In this talk, I will present the results of our recent paper arXiv:2512.13794 for a complete classification of the Feynman-integral geometries at two-loop order in four-dimensional Quantum Field Theory with standard quadratic propagators. Concretely, we consider a finite basis of integrals in the ’t Hooft–Veltman scheme, i.e. with D-dimensional loop momenta and four-dimensional external...
I will present recent progress in extending the tropical integration framework originally proposed by Borinsky to Feynman integrals with numerators. This generalisation is essential for applications in gauge theories and significantly broadens the scope of tropical Monte Carlo methods to physically relevant observables in Quantum Chromodynamics (QCD) and N=4 super Yang–Mills theory (SYM).

In recent years, it has been observed that period integrals of Calabi-Yau manifolds, which originate from the compactification of string theory, appear in the classical scattering of black holes. These mathematical structures were observed for the first time at the fifth post-Minkowskian (5PM) order. In my talk, I will provide a brief introduction to these objects, particularly from a...
